From the vendor

Menatone's King of the Britons, a Marshall-style high-gain distortion from the maker known for amp-in-a-can pedals. The schematic shows six J201 JFET stages modeling a tube preamp: three cascaded gain stages with a Gain pot, a source follower driving a Marshall-type High/Mid/Low tone stack, then a Master pot and two more JFET stages before the Level control. The author liked it but preferred runoffgroove's Thor.
